Calcium silicate insulating board
Introduction
Calcium silicate is mainly made by silicon dioxide and calcium oxide powder with wood fiber as reinforcing material. It is a new environment-friendly insulation material, non-toxic and no poisonous substance such as asbestos, sulfur and chlorine.
There're
2 types, ordinary microporous calcium silicate of 650°C resistant and
high end refractory calcium silicate of 1050°C resistant.
Characteristic
1.Low thermal conductivity, high insulation ability
2.Protect the equipment, hlep the equipment longer life span
3.Without asbestine, safe and clean
4.Good durability, can withstand continuous thermal burden under high temperature
